Review or remove an attachment before sending
Review or remove an attachment before sending in Cortex Chat: practical steps, setting explanations, result checks and troubleshooting.
A preview is the last chance to check the selected file and its caption. A local preview does not prove an upload or send has completed. Sensitive documents should be checked before they enter the conversation context.
Before you start
The active composer determines where text, mentions and attachments will be sent. A private assistant panel can sit beside a shared conversation, so check the heading as well as the visible text. Inspect the file or recording before sending it; a local preview is not a completed upload. Chat validates a single attachment and rejects empty, oversized or unsupported files. Receipt state describes the message transport, not the success of a task requested inside it. If the result is uncertain, inspect the existing conversation and any external destination before retrying. This is especially important when a message asks the assistant to send, book or create something.
Step-by-step
- Select the attachment and open the preview shown by the composer.
- Inspect the name, visible content and any text that will accompany it.
- Cancel or remove the pending file if it is wrong; otherwise confirm the send through the displayed control.
What the settings mean
| Control or state | Meaning |
|---|---|
| Composer | The current destination for text and pending media. |
| Preview | Content selected locally and still awaiting the send action. |
| Receipt | Sending, failed, sent, delivered or read information. |
| Task result | The separate artifact or external action requested in the message. |
Check the result
Only the intended content is sent, with a clear question or caption.
If it does not work
If a preview cannot render, use the supported download or file information rather than assuming the file is empty. Check the actual attachment before retrying an upload.
Continue with the right context
